What is the difference between a lithium battery and a battery, why are they different in size

- Sep 07, 2019-

The lithium battery is mainly composed of two large blocks, the battery core and the protection board PCM (the power battery is generally called the battery management system BMS), and the protection board is mainly composed of a protection chip (or management chip), a MOS tube, a resistor, a capacitor, and a PCB board. The battery core is equivalent to the heart of a lithium battery, and the management system is equivalent to the brain of a lithium battery. The battery core is mainly composed of a positive electrode material, a negative electrode material, an electrolyte, a diaphragm, and an outer casing.

There are certain differences between the two, and the natural size is different.
